Running multiple Node (Express) apps on same port
提问by user1437328
I have multiple Node applications (build on Express framework).
我有多个 Node 应用程序（构建在 Express 框架上）。
Now I have placed them like this -
现在我把它们放在这样的位置——
/var/www/app1/var/www/app2/var/www/app3
/var/www/app1/var/www/app2/var/www/app3
Now I want to run these 3 apps on the same port (say 8080). Is that possible ?
现在我想在同一个端口（比如 8080）上运行这 3 个应用程序。那可能吗 ？
One thing to note is that, Each app has common routes like these -
需要注意的一件事是，每个应用程序都有这样的常见路线 -
app.get('/', func...);app.get('/about', func...);app.post('/foo', func...);app.post('/bar', func...);
app.get('/', func...);app.get('/about', func...);app.post('/foo', func...);app.post('/bar', func...);
Basically I want to do it like you can do with Apache/PHP setup.
基本上我想像使用 Apache/PHP 设置那样做。
So with a LAMP stack when you have -
所以当你有一个 LAMP 堆栈时 -
/var/www/app1/var/www/app2/var/www/app3
/var/www/app1/var/www/app2/var/www/app3
You can easily access them as different apps from -
您可以轻松访问它们作为不同的应用程序 -
localhost/app1localhost/app2localhost/app3
localhost/app1localhost/app2localhost/app3

You could run them as seperate apps listening to different ports and then have a proxy (like https://github.com/nodejitsu/node-http-proxy/) serving everything on 8080 depending on the requested URL.
您可以将它们作为单独的应用程序运行，侦听不同的端口，然后使用代理（如https://github.com/nodejitsu/node-http-proxy/）根据请求的 URL 为 8080 上的所有内容提供服务。

喜欢：
var options = {
router: {
'foo.com/baz': '127.0.0.1:8001',
'foo.com/buz': '127.0.0.1:8002',
'bar.com/buz': '127.0.0.1:8003'
}
};
Works like charm for me ( http://nerdpress.org/2012/04/20/hosting-multiple-express-node-js-apps-on-port-80/). I wasn't so keen on having them mounted as sub-apps, as suggested in the comments because i wanted them to run independently...
对我来说就像魅力一样（http://nerdpress.org/2012/04/20/hosting-multiple-express-node-js-apps-on-port-80/）。我不太热衷于将它们安装为子应用程序，正如评论中所建议的那样，因为我希望它们独立运行......

You can create one main app(say app) parallel to you apps, and have it initializing the secondary apps (in your case app1, app2, app3) using
您可以创建一个与您的应用程序并行的主应用程序（比如应用程序），并使用它初始化辅助应用程序（在您的情况下为 app1、app2、app3）
app.use('<the_context_you_need>', require('./app1/yourApp.js')
All your apps (app1, app2, app3) need to create app and export it by using
您所有的应用程序（app1、app2、app3）都需要创建应用程序并使用
var app = module.exports = express();
You need not create instance of server or call app.listen in all the subapps; all the sub-apps can be served via main app listen port.
您无需在所有子应用程序中创建服务器实例或调用 app.listen；所有子应用程序都可以通过主应用程序监听端口提供服务。
